Provided is a system and method for tuning an array of sensors to enable selection of the most suitable sensors for a target application. After extracting features from sensor raw data, the extracted features are ranked with gradient boosting decision trees to assign an importance value to each extracted feature. A threshold value for the entire set of extracted features is calculated and an importance score is calculated for the individual sensors of the array. Individual sensors with an importance score on or above the threshold value are selected for the target application.

Sensor tuning&#x2014;sensor specific selection for IoT&#x2014;electronic nose application using gradient boosting decision trees

Provided is a gas sensor system with a gas sensor, and a microprocessor programmed to control the gas sensor with at least two operational modes. The first operational mode controls the gas sensor from a baseline level through analyte detection. Upon initiation of the recovery phase after analyte withdrawal, the gas sensor system switches to the second operational mode, which changes conditions of the gas sensor to (i) accelerate removal of the analyte from the gas sensor and (ii) accelerate recovery of the gas sensor output towards the baseline level. When no further analyte is detected, the gas sensor switches back to the first operational mode or to an additional operational mode to complete recovery.

Adaptive sensor temperature control for fast recovery

A system, according to one embodiment, includes: a plurality of tape reels; and a tape drive configured for reading data from tape stored on at least one of the plurality of tape reels. At least some of the tape reels have a tape wound thereon and a spring-like clip coupled to a free end of the tape. Moreover, the clip is selectively positionable in a wrapped position where the clip wraps around a portion of the tape when the tape is wound onto the reel, thereby holding the portion of the tape in place on the reel.

Spring clip leader and housing for magnetic tape

Various embodiments relate to methods for loading and unloading a tape storage medium. According to one embodiment, a method for loading a tape storage medium includes positioning a mechanized take-up reel with respect to a tape supply reel, positioning a feature coupled to a tape storage medium on the tape supply reel with respect to the mechanized take-up reel, rotatably decoupling an inner hub of the mechanized take-up reel from an outer hub of the mechanized take-up reel, extending a tongue of the mechanized take-up reel, engaging the tongue with the feature, retracting the tongue and feature into the outer hub, and nonrotably coupling the inner hub with the outer hub.

Mechanized take-up reel and method for loading and unloading a tape storage medium

A spring-like clip for a spool of tape, one end of the clip being attached to one end of the tape, and another end of the clip having an engagement feature that allows the clip to be pulled from the spool. The clip is configured to curve around the spool to hold the tape in place. In one general embodiment, a product includes a reel, a tape coupled to the reel, and a spring-like clip coupled to a free end of the tape. The clip is selectively positionable in a wrapped position where the clip wraps around a portion of the tape when the tape is wound onto the reel, thereby holding the portion of the tape in place on the reel. Systems for using various types of such products are presented, and generally include a tape drive configured for reading data from tape stored on such products.

Various embodiments relate to apparatuses and methods for loading and unloading a tape storage medium. In one embodiment, an apparatus for such purpose includes a mechanized take-up reel. The mechanized take-up reel includes an inner hub, an outer hub being selectively nonrotatably coupleable with the inner hub (where at least one of the hubs is coupled to a rotating mechanism), a tongue coupled to the inner hub, and a slot in the outer hub for permitting the tongue to extend beyond a periphery of a tape engaging surface of the outer hub upon relative rotation between the inner and outer hubs.

An apparatus usable as a chucking device to temporarily couple two mechanical objects together. In one embodiment, the apparatus includes an arbor configured to receive an at least partially ferromagnetic object; and a magnet assembly. The magnet assembly includes multiple permanent magnets mounted in a soft ferromagnetic enclosure. The magnet assembly is rotatably coupled to the arbor such that the magnet assembly and the arbor are positionable relative to one another in locking and unlocking positions upon relative rotation therebetween. The magnet assembly is configured to exert a pulling force on the object in the locking position and a lesser force in the unlocking position.
